Description
1. MODEL CODE DEFINITION
CACR stands for Yasnac VS800 full digital AC servo amplifier for CNC feed axis closed-loop motion control.SR supports three configurable control modes: ±10VDC analog speed control, torque control and differential pulse position control via internal parameter setup.10 means rated matched servo motor power 1.0kW with continuous rated output current 7.6Arms under AC200V class input.BZ represents upgraded feedback PCB and housing; CN2 hardware supports both incremental encoder and serial absolute encoder feedback, equipped with standard built-in dynamic braking circuit, different from BY incremental-only circuit design.1 specifies power supply standard: three-phase AC200~230V main power plus independent single-phase AC200~230V separated control power supply.S refers to single CN2 encoder feedback channel configuration.M is special customized fixed firmware version with partial core gain, encoder and I/O parameters factory preset and write-locked; parameter adjustable scope is narrower than standard G universal firmware, no extra C/E/Y suffix marking.
2. ELECTRICAL SPECIFICATIONS
Main input power: three-phase AC200V~230V, allowable voltage fluctuation -15%~+10%, compatible with 50Hz/60Hz industrial power grid. Control power requires independent single-phase AC200~230V separate wiring to isolate surge interference from main power circuit.Continuous rated output current:7.6Arms; 150% overload can run continuously for 60 seconds, 300% instantaneous peak overload limited within 3 seconds for motor startup acceleration. Normal DC bus operating voltage DC280V~DC320V; terminals P and BN are reserved for external regenerative braking resistor connection for frequent rapid deceleration and heavy-duty machining.The drive adopts IGBT sine-wave PWM modulation with maximum output frequency up to 300Hz, encoder matching parameters preset by M-version factory program.
3. INSTALLATION & ENVIRONMENT REQUIREMENT
Operating ambient temperature:0℃ ~ +55℃; storage temperature: -20℃ ~ +70℃. Working environment relative humidity 5%~80%RH without dew condensation; enclosure protection grade IP20 and vertical upright installation inside electrical cabinet is mandatory.Max allowable installation altitude below 1000 meters above sea level; derated operation is necessary for mounting height over 1000m. Anti-vibration specification:10Hz~55Hz with 0.5mm single amplitude during continuous operation; net weight approx 3.1kg.
4. CONTROL PERFORMANCE AND FEATURES
Speed adjustment ratio reaches 1:5000, full-load steady speed deviation controlled within ±0.01%. Built-in digital notch filter effectively suppresses mechanical resonance and low-speed crawling during frequent start-stop cycles.Dual command input available: ±10VDC analog speed/torque signal and differential pulse position command signal; CN2 feedback port can switch between incremental and serial absolute encoder via limited editable auxiliary parameters under M firmware restriction.Auto-tuning function is partially locked: complete full automatic motor parameter identification is unavailable, only minor fine-tuning of partial gain parameters is allowed for slight on-site mechanical matching; most CN1 I/O definition follows factory fixed setting of M version and cannot be freely redefined via parameters.Onboard RS422 serial communication supports real-time runtime data reading and historical fault code inquiry; core locked parameters cannot be modified or uploaded via communication cable.
5. TERMINAL AND CONNECTOR DESCRIPTION
R/S/T: three-phase main AC power input terminals; U/V/W: three-phase output terminals connecting servo motor stator cable; P/BN: external regenerative brake resistor wiring terminals for regenerative energy dissipation during fast deceleration and repeated emergency stop.CN1: opto-isolated digital I/O terminal block with factory fixed signal definition set by M firmware, arbitrary modification of I/O allocation is restricted.CN2: multi-purpose encoder feedback connector supporting both incremental and serial absolute encoder wiring as per matched motor specification.
6. PROTECTION FUNCTIONS
Complete built-in protection includes overcurrent protection, DC bus overvoltage/undervoltage protection, drive overheat protection, encoder disconnection protection and motor overload protection. The servo automatically saves latest 10 groups of historical fault codes for maintenance check; M-version preset parameters will not be erased after power-off or fault reset operation.Built-in standard dynamic braking circuit handles regular deceleration energy consumption; external regenerative resistor must be fitted between P and BN terminals under continuous heavy cutting and repeated emergency stop working conditions.
7. REPLACEMENT INSTRUCTION
CACR-SR10BZ1SM cannot be directly substituted by BZ series SF/G standard models due to M-version unique locked firmware and preset parameters; only identical full part number CACR-SR10BZ1SM can realize plug-and-play replacement.
8. ROUTINE MAINTENANCE GUIDE
Check tightness of power cables, motor cable and CN1/CN2 connectors before every startup to eliminate poor-contact-induced faults. Clean radiator fin dust every 3~6 months to guarantee heat dissipation efficiency and avoid overheat alarm.Cut off all AC power supply and wait over 15 minutes for internal DC bus capacitor full discharge before disassembling drive housing for maintenance to prevent electric shock hazard. Arbitrary full factory parameter reset is forbidden to avoid loss of M-version factory preset data and subsequent machine malfunction.
9. BASIC FAULT TROUBLESHOOTING
Overheat alarm mainly arises from radiator dust clogging, poor cabinet ventilation or long-term overloaded running. Encoder fault alarm mostly caused by loose CN2 plug, damaged feedback cable or unauthorized modification of locked encoder matching parameters.Overvoltage alarm occurs during frequent heavy-load rapid deceleration; resolve by installing external regenerative resistor between P and BN terminals. Parameter write failure when modifying M-version locked core parameters belongs to normal firmware protection instead of drive hardware damage. Overload alarm triggers when actual mechanical load exceeds motor rated output; inspect stuck transmission mechanism or reduce processing load accordingly.
